Abstract：
The collision dynamics and yields of the multifragmentation in intermediate energy heavy ion collisions are simulated within the frame of the modified quantum molecular dynamics(MQMD ).With this new MQMD,it is found that the obvious improvements about the agreements between the experimental data and the simulating results for the fragment production by means of MDI and Pauli potential are achieved.Meanwhile the different influences of MDI and Pauli potential on the collision dynamics of intermediate energy heavy ion collisions are obtained.Finally the possible reasons for the discrepancies between the experimental data and the present simulating results and remedies of these deficiencies are discussed in detail.
